Definitions

  • the present invention relates to a method for reducing the amount of die buildup associated with the production of polyolefin based elastic fiber and for improving the unwind or release characteristics of such fiber.
  • the method involves the use of polydimethylsiloxane (PDMSO) in the polyolefin resin.
  • PDMSO polydimethylsiloxane
  • the fiber After the fiber has been formed, the fiber is typically wound on bobbins or spools for later use. Another problem which has been observed with some of these packages is that the fiber tends to stick to the package during unwinding leading to tangles and breaks. It is a goal of the present invention to improve the release or unwind characteristics of the fiber from these packages.
  • FIG. 1 is a graph demonstrating the frequency dies needed to be cleaned using different levels of PDMSO.
  • FIG. 2 is a graph demonstrating the effect of PDMSO and lubricating oil on the releasability factor.
  • FIG. 3 demonstrates the load at break and elongation at break of fibers made in accordance with the present invention.
  • the present invention is a way of improving the fiber spinning and unwinding properties for any polyolefin-based fiber.
  • the olefin polymer for use in the present invention can be any olefin based material capable of forming a fiber, including ethylene-alpha olefin interpolymers, substantially hydrogenated block polymers, propylene alpha olefin interpolymers (including propylene ethylene copolymers), styrene butadiene styrene block polymers, styrene-ethylene/butene-styrene block polymers, ethylene styrene interpolymers, polypropylenes, polyamides, polyurethanes and combinations thereof.
  • the homogeneously branched ethylene polymers described in U.S. Pat. No. 6,437,014 which is hereby incorporated by reference in its entirety), particularly the substantially linear ethylene polymers, are particularly well suited for use in this invention.
  • the present invention is particularly useful for fibers made form linear low density ethylene alpha-olefin copolymers, most preferably those having a density in the range of 0.80 to 0.89 g/cc (as determined by ASTM 1505) and a melt index from 0.5 dg/min to 10 dg/min (as determined by ASTM D1238).
  • Preferred polyolefin materials are sold under the AFFINITY trade name by The Dow Chemical Company, the EXACT trade name sold by Exxon-Mobil Company, or the TAFMER trade name sold by Mitsui Chemical Company.
  • the most preferred polymer is polyethylene with an octene comonomer content of 5 to 30 percent by weight, having a density of about 0.875 g/cc and a melt index of about 3 dg/min.
  • the PDMSO used can be a hydroxyl-terminated, ultra high molecular weight poly(dimethylsiloxane).
  • the PDMSO preferably has a molecular weight of approximately 2 million.
  • the PDMSO is conveniently added to the polymer composition in the form of a masterbatch, in a polyethylene based carrier material, in an amount so that the final composition contains from 0.1 percent to 5 percent PDMSO by weight, more preferably from 0.3 percent to 2 percent by weight. Most preferably the final composition contains should contain no less than 0.5 percent by weight PDMSO.
  • the PDMSO can be added to the polymer in any way known to the art.
  • the PDMSO is ideally added prior to extrusion/fiber formation in order to get the benefit of both reduce die build-up and improved unwinding characteristics, but may be added after fiber formation, for example in a spin finish, if only improved unwinding performance is desired.
  • the PDMSO may be added to the polyolefin material via a masterbatch with additional polyolefin material as the carrier medium.
  • the addition of the PDMSO reduces die build-up in the extrusion of the polymer and also improves the release characteristics of the fiber from the packages or spools of the fiber. This latter effect can be further improved with the external application of a spin finish.
  • the spin finish can be any lubricating oil and is preferably selected from the group comprising silicones, mineral oils, ester oils with a viscosity range of 1 to 120 cSt, and blends thereof.
  • the method of the present invention leads to spools or packages having improved unwinding or release characteristics.
  • a releasability test was created.
  • the package/spool was placed in contact with a feed or drive roller (friction roller) rotating at a set speed (as provided by spinning the given roller at a speed of 30 rpm), and the filament was unwound onto a winding roller initially rotating at a speed set at three times the speed of the feed roller (that is the draft was 3 ⁇ ). At this speed and draft, no sticking was observed.
  • the winding roller rotational speed was then gradually reduced until the point where the unwinding fiber sticks as indicated by the fiber no longer being removed tangentially from the package/spool.
  • RF releasability factor
  • Fibers with the best releasability have very low values on this test (that is they do not stick even at low speeds). It is preferred that the method of the present invention reduce the release-ability value by at least twenty percent (for example if the release-ability factor for a particular fiber was 80 percent without the use of PDMSO, then the method of the present invention will preferably result in a releasability factor of 66 percent or less).
  • Another aspect of the present invention is an elastic polyolefin-based fiber package having a releasability of less than 100 percent, more preferably less than 50 percent, most preferably less than 30 percent using the test just described.
  • fiber was prepared from a base polymer prepared using an INSITE Constrained Geometry Metallocene catalyst.
  • the base polymer was polyethylene with an octene comonomer content of about 35 percent to give a density of 0.875 g/cc with a melt index of 3.0+/ ⁇ 0.20 dg/min as determined using ASTM D1238.
  • a masterbatch of 40 percent by weight PDMSO in an ethylene styrene interpolymer was prepared.
  • the master batch was then dry blended into the base polymer to provide the desired level of PDMSO in the fiber.
  • 3 levels of PDMSO were evaluated, 0 percent. 0.5 percent and 1 percent.
  • the polymer was then melt spun into fibers at a melt temperature of 270° C. Each polymer formulation was run for 8 hours and the number of times the spinnerets (dies) had to be cleaned is reported in FIG. 1 .
  • the load at break (as determined by DIN 53 835 Part 1 and elongation at break (as determined by DIN 53 835 Part 1) of these fibers were measured at 100 mm grip distance at 500 nm/min separation speed. There was no significant loss of physical properties when using this internal and external lubrication method, as demonstrated in FIG. 3 .
